Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an air conditioner swing blade mechanism and an air conditioner. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, air conditioners have been widely popularized, and the requirements for the functions of air conditioners are becoming more and more refined. Among them, the requirements for wind direction adjustment of air conditioners are becoming more and more detailed. The left and right swing of the air conditioner is usually achieved by the swing mechanism, which is also the key component for adjusting the air outlet direction of the air conditioner. The swing blade mechanism of the air conditioner is not only related to the air supply efficiency of the air conditioner, but also directly affects the user experience.

[0003] The swing mechanism usually includes a motor, a swing blade connecting rod and multiple swing blades. The swing blade connecting rod extends along the length direction of the air outlet of the air conditioner indoor unit and can be translated left and right. Multiple swing blades are arranged on the swing blade connecting rod at intervals along the extension direction of the swing blade connecting rod (i.e., the left and right direction). The motor drives one of the swing blades to swing left and right, and then drives all the swing blades to swing left and right synchronously through the swing blade connecting rod to achieve left and right swinging wind.

[0004] In the above-mentioned swing wind mechanism, the swing blade connecting rod mostly adopts a crank-connecting rod mechanism, which makes the structure of the swing blade connecting rod more complicated and occupies a larger installation space. At the same time, it also requires a large torque of the swing blade motor and the energy consumption will increase accordingly. When the mechanism moves, the crank-connecting rod mechanism formed by the swing blade connecting rod is prone to pause, jamming and other phenomena during operation. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an air-conditioning swing blade mechanism and an air conditioner to solve the problem that a crank connecting rod mechanism formed by a swing blade connecting rod is prone to pause and jam during operation.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: an air conditioner swing blade mechanism, including a plurality of swing blades, a swing blade bracket and a swing blade connecting rod driving the plurality of swing blades to swing, and also including:

[0007] A slider, one end of which is fixedly connected to the end of the swing blade connecting rod, and the other end of which is provided with a sliding groove;

[0008] A motor connecting rod, one end of the motor connecting rod is fixedly connected to the motor, and the other end of the motor connecting rod is slidably connected to the slide groove of the slider, the sliding direction of the motor connecting rod end in the slide groove is perpendicular to the horizontal movement direction of the swing blade connecting rod, and the rotating surface where the motor connecting rod is located is parallel to the horizontal movement vertical surface where the swing blade connecting rod is located.

[0009] The technical principle of the utility model is: the motor is energized to drive the motor connecting rod to rotate around the power output end, and the end of the motor connecting rod cooperates with the slide groove of the slider, and the slider and the swing leaf connecting rod are driven to move left and right through the combined movement of the sliding and rotating pairs. When the swing leaf connecting rod moves horizontally, the swing leaf connecting rod drives the swing leaf to rotate left and right; in this process, the torque between the slider and the motor connecting rod is reduced through the cooperation of rotation and sliding between the slider and the motor connecting rod, which can reduce the output force of the motor. A motor with a smaller torque can be used under the same mechanism, and the sliding is smoother and less prone to jamming.

[0010] Furthermore, it also includes:

[0011] The first limit block;

[0012] The second limit block; when the swing blade swings to the extreme position on one side, the first limit block abuts against one side of the motor connecting rod; when the swing blade swings to the extreme position on the other side, the second limit block abuts against the other side of the motor connecting rod.

[0013] Through the above arrangement, the first limit block and the second limit block can control the circumferential rotation angle of the motor connecting rod, thereby preventing the motor connecting rod from rotating excessively and also preventing the swing blade connecting rod from moving excessively horizontally.

[0014] Furthermore, a slider boss which can be embedded in the slider slot is fixedly provided on one end of the motor connecting rod close to the slot.

[0015] Through the above arrangement, the slider boss can make the motor connecting rod and the slider groove cooperate more smoothly, and the slider boss is also more convenient for the slide groove to cooperate closely, thereby realizing stable power transmission.

[0016] Furthermore, the slider boss is cylindrical, and a caulking is provided at one end of the slider boss away from the motor connecting rod, which allows the end of the slider boss to be compressed and embedded in the sliding groove.

[0017] Through the above arrangement, it is convenient to embed the slider boss into the slide groove by pinching the end of the slider boss, making the coordinated installation between the slider and the motor connecting rod more convenient and efficient, thereby improving the installation efficiency of the air conditioner swing blade mechanism.

[0018] Furthermore, a mounting flat hole for mounting with the motor power output end is provided on one end of the motor connecting rod connected with the motor, and a rib for interference fit with the motor power output end is provided in the mounting flat hole of the motor connecting rod.

[0019] Through the above arrangement, the motor connecting rod can be more easily installed in coordination with the power output end of the motor through the installation flat hole and the ribs, so that the power transmission between the motor connecting rod and the motor is stable.

[0020] Furthermore, a clip is provided on one end of the sliding block close to the swing leaf connecting rod, and a slot which is engaged with the clip is provided on the end of the swing leaf connecting rod.

[0021] Through the above arrangement, the clip can be more easily engaged with the slot on the swing blade connecting rod by means of an engaging manner, so that the installation and cooperation between the slider and the swing blade connecting rod are convenient, thereby improving the assembly efficiency.

[0022] Furthermore, the slide groove is a waist-shaped hole.

[0023] Through the above arrangement, when the slide groove and the slider boss are slidably matched, the waist-shaped hole can more easily guide the sliding of the slider boss, so that the matching between the slider and the motor connecting rod is accurate.

[0024] Furthermore, one side of the swing blade is rotatably connected to the surface of the swing blade bracket, the surface of the swing blade is perpendicular to the surface of the swing blade bracket, a rotating shaft is fixedly installed on the side of the swing blade close to the swing blade connecting rod, the axis of the rotating shaft is parallel to the rotation axis between the swing blade and the swing blade bracket, an elastic clamping ring is provided on the lower end of the rotating shaft, and a groove for the rotating shaft to be embedded is provided on the side wall of the swing blade connecting rod, and the elastic clamping ring can be against the swing blade connecting rod.

[0025] Through the above arrangement, the rotating shafts of several swing blades are opposite to the embedding grooves on the swing blade bracket in turn, the middle part of the rotating shaft is embedded in the embedding groove, the embedding groove is abutted against the outer wall of the rotating shaft, and the swing blade bracket is abutted against the elastic clamping ring, thereby realizing the rapid installation and connection between several swing blades and the swing blade bracket.

[0026] Furthermore, the first limit block is located on the upper side of the slider, the first limit block is located on the side close to the swing blade connecting rod, and the second limit block is located on the lower side of the slider.

[0027] Through the above-mentioned setting, when the swing blade connecting rod moves horizontally to the extreme position, the swing blade also rotates synchronously to the extreme position set on one side. At this time, the slider drives one end of the motor connecting rod to the position of the first limit block; otherwise, the motor connecting rod and the second limit block are offset, and the first limit block and the second limit block block the motor connecting rod to achieve precise limiting effect.

[0028] The utility model also intends to provide an air conditioner, including an air conditioner inner machine housing and an air conditioner swing blade mechanism, the air conditioner inner machine housing is provided with an air conditioner air outlet, and the air conditioner swing blade mechanism is installed at the air conditioner air outlet of the air conditioner inner machine housing.

DETAILED DESCRIPTION

[0036] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0037] Example 1

[0038] This embodiment is basically Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the embodiment of the utility model proposes an air conditioner swing blade mechanism, including a plurality of swing blades 20, a swing blade bracket 30, a swing blade connecting rod 40 for driving the plurality of swing blades 20 to swing, a first limit block 501, a second limit block 502, a slider 60 and a motor connecting rod 70, as shown in FIG. Figure 1 As shown, a clip 601 is integrally formed on the left end of the slider 60, and a slot 401 that is engaged with the clip 601 is provided on the end of the swing blade connecting rod 40. The setting direction of the slot 401 is perpendicular to the horizontal movement direction of the swing blade connecting rod 40. After the clip 601 is engaged with the slot 401, the left end of the slider 60 is fixedly connected to the end of the swing blade connecting rod 40.

[0039] At the same time Figure 1 and 3As shown, a slide groove 602 is provided on the right end of the slider 60, and the slide groove 602 is a waist-shaped hole; a mounting flat hole 702 installed with the power output end of the motor 80 is provided at the upper end of the motor connecting rod 70, and a rib 703 with an interference fit with the power output end of the motor 80 is provided in the mounting flat hole 702 of the motor connecting rod 70, so that the upper end of the motor connecting rod 70 is fixedly connected to the motor 80; a slider 60 boss which can be embedded in the slide groove 602 of the slider 60 is integrally formed at the lower end of the motor connecting rod 70, and the slider 60 boss away from the end of the motor connecting rod 70 is a mushroom head cylinder, and the middle of the end of the slider 60 boss is broken to form a caulking, and the slider 60 boss is in sliding contact with the slide groove 602 of the slider 60; at the same time, the sliding direction of the end of the motor connecting rod 70 in the slide groove 602 is perpendicular to the horizontal movement direction of the swing leaf connecting rod 40, and the rotating surface where the motor connecting rod 70 is located is parallel to the horizontal movement vertical surface where the swing leaf connecting rod 40 is located.

[0040] like Figure 2 As shown, the first limit block 501 is located on the upper left side of the motor connecting rod 70, the first limit block 501 is located on the side close to the swing blade connecting rod 40, and the second limit block 502 is located on the upper right side of the motor connecting rod 70. When the swing blade 20 swings to the extreme position on the left side, the first limit block 501 and the slider 60 are set to abut against the left side of the motor connecting rod 70; when the swing blade 20 swings to the extreme position on the right side, the second limit block 502 is abutted against the right side of the motor connecting rod 70.

[0041] like Figure 3 and 4 As shown, one side of the swing blade 20 is rotatably connected to the surface of the swing blade bracket 30, and the surface of the swing blade 20 is perpendicular to the surface of the swing blade bracket 30. A rotating shaft 201 is fixedly installed on the side of the swing blade 20 close to the swing blade connecting rod 40. The axis of the rotating shaft 201 is parallel to the rotation axis between the swing blade 20 and the swing blade bracket 30. An elastic clamping ring 202 is provided on the lower end of the rotating shaft 201, and an embedding groove 402 for the rotating shaft 201 to be embedded is provided on the side wall of the swing blade connecting rod 40, and the elastic clamping ring 202 can be against the swing blade connecting rod 40.

[0042] When installing the air conditioner swing blade mechanism in this embodiment, the rotating shafts 201 of the plurality of swing blades 20 are aligned with the embedding grooves 402 on the swing blade bracket 30 in sequence, and the middle part of the rotating shaft 201 is embedded in the embedding groove 402. The embedding groove 402 abuts against the outer wall of the rotating shaft 201, and the swing blade bracket 30 abuts against the elastic clamping ring 202, so as to realize the rapid installation and connection between the plurality of swing blades 20 and the swing blade bracket 30; then the clamp 601 on the end of the slider 60 is embedded in the clamping groove 401 of the swing blade bracket 30, The slider 60 and the swing blade bracket 30 can be quickly installed; the slider 60 boss is then installed into the slide groove 602 of the slider 60 through the end of the slider 60 boss, so that the slider 60 is connected with the motor connecting rod 70 to form a composite structure of sliding and rotating pairs; finally, the power output end of the motor 80 is installed into the installation flat hole 702 of the motor connecting rod 70, and the installation and coordination between the various structures can be quickly completed. The installation and coordination are accurate, and the snap-on installation method can effectively improve the installation production efficiency.

[0043] When the air conditioner swing blade mechanism is in use, the motor 80 is energized to drive the motor connecting rod 70 to rotate around the power output end. The motor connecting rod 70 cooperates with the slide groove 602 of the slider 60 through the boss of the slider 60, and drives the slider 60 and the swing blade connecting rod 40 to move left and right through the combined movement of the sliding and rotating pairs. When the swing blade connecting rod 40 moves horizontally, the swing blade connecting rod 40 drives the swing blade 20 to rotate left and right through the cooperation of the embedded groove 402 and the rotating shaft 201.

[0044] When the swing blade connecting rod 40 moves horizontally to the extreme position on the left side, the swing blade 20 also rotates synchronously to the extreme position set on the left side. At this time, the slider 60 drives the left end of the motor connecting rod 70 to the position of the first limit block 501, and the first limit block 501 blocks the motor connecting rod 70 to achieve the limiting function; similarly, when the swing blade connecting rod 40 moves horizontally to the extreme position on the right side, the swing blade 20 also rotates synchronously to the extreme position set on the right side, and the slider 60 drives the left end of the motor connecting rod 70 to the position of the second limit block 502. The second limit block 502 blocks the motor connecting rod 70 to achieve the limiting function, thereby preventing the motor connecting rod 70 from rotating excessively.

[0045] At the same time, in this process, through the rotation and sliding cooperation between the slider 60 and the motor connecting rod 70, the torque between the slider 60 and the motor connecting rod 70 is reduced, the output force of the motor 80 can be reduced, and a motor 80 with a smaller torque can be used under the same mechanism, and the sliding is smoother and less prone to jamming. The close cooperation between the slider 60 and the motor connecting rod 70 reduces the volume required by the entire air-conditioning swing blade mechanism and makes it easier to install.

[0046] Example 2

[0047] The difference between Example 2 and Example 1 is basically as follows: an air conditioner is provided, including an air conditioner inner machine housing 1 and an air conditioner swing blade mechanism, the air conditioner inner machine housing 1 is provided with an air conditioner air outlet 11, and the air conditioner swing blade mechanism is installed at the air conditioner air outlet 11 of the air conditioner inner machine housing 1.

[0048] When the air conditioner in this embodiment is in use, when adjusting the wind direction of the air conditioner, the swing blade 20 on the air conditioner swing blade mechanism can be flipped more smoothly under the control of the slider 60 and the motor connecting rod 70, and the direction adjustment of the entire swing blade 20 is more flexible and smooth, which can effectively improve user satisfaction.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
