DETAILED DESCRIPTION

[0047] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0048] First embodiment

[0049] See also Figure 1 and Figure 2 This embodiment provides a lifting air outlet adjustment device 10, which is suitable for an air conditioner indoor unit. It can adjust the air outlet direction of the air outlet 330 of the air conditioner indoor unit and improve the air outlet adjustment effect to prevent cold air from falling to the ground and blowing on people, and improve physical comfort.

[0050] The lifting air outlet adjustment device 10 provided in this embodiment includes a panel 100, a lifting mechanism 200 and a middle frame 300. The lifting mechanism 200 includes a transmission connecting rod 210, a lifting driving assembly 230 and a mounting seat 250. The lifting driving assembly 230 is connected to the mounting seat 250. A seat body mounting groove 310 is provided on the middle frame 300. The mounting seat 250 can be detachably assembled in the seat body mounting groove 310. The lifting driving assembly 230 is transmission-connected with the transmission connecting rod 210. The transmission connecting rod 210 is connected to the panel 100. An air outlet 330 is also provided on the middle frame 300. The transmission connecting rod 210 is used to drive the panel 100 to descend relative to the air outlet 330 under the drive of the lifting driving assembly 230 to block the air outlet 330. The transmission connecting rod 210 is also used to drive the panel 100 to rise relative to the air outlet 330 under the drive of the lifting driving assembly 230 to remove the blocking of the air outlet 330.

[0051] In this embodiment, the air outlet 330 is arranged at the bottom of the middle frame 300, the mounting seat 250 is arranged above the air outlet 330, and the width of the panel 100 in the vertical direction is equivalent to the width of the middle frame 300 in the vertical direction, so that the panel 100 can block the front of the air outlet 330 when it is in a closed state. Specifically, when the panel 100 is lowered, it blocks the air outlet 330, and at this time, the air outlet 330 discharges air normally, and the air outlet direction is tilted downward. When the panel 100 rises driven by the lifting drive assembly 230, the air outlet 330 is unblocked, so that the air outlet 330 can discharge air forward, and then the air outlet direction is tilted forward, which effectively adjusts the air outlet direction to prevent cold wind from falling to the ground and blowing people.

[0052] It should be noted that two seat mounting grooves 310 are provided on the middle frame 300 in this embodiment, and the two seat mounting grooves 310 are respectively located at the two ends of the air outlet 330, so that two lifting mechanisms 200 can be assembled to perform lifting from both ends of the panel 100, thereby ensuring the stability of the lifting.

[0053] See also Figures 3 to 5The transmission link 210 includes an upper swing rod 211 and a connecting rod 213. The connecting rod 213 is connected to the panel 100. One end of the upper swing rod 211 is hinged to the top of the connecting rod 213, and the other end is transmission-connected to the lifting drive assembly 230, so as to swing under the drive of the lifting drive assembly 230 and drive the connecting rod 213 to rise or fall relative to the mounting seat 250. The upper swing rod 211 is connected to the panel 100 by the connecting rod 213, and the upper swing rod 211 is hinged to the connecting rod 213. The upper swing rod 211 moves under the drive of the lifting drive assembly 230. In the process of driving the connecting rod 213 to rise and fall, the connecting rod 213 can rotate relative to the upper swing rod 211, so that the panel 100 can maintain a vertical state under the action of gravity during the movement, avoiding the panel 100 from opening too much, reducing the travel interference range of the panel 100, and avoiding interference with environmental components during the rising process of the panel 100.

[0054] In this embodiment, the upper swing arm 211 swings within a certain angle range under the driving action of the lifting drive assembly 230. Specifically, the upper swing arm 211 swings within an obtuse angle range. When the upper swing arm 211 swings to the lower limit position, the panel 100 is attached to the middle frame 300 and blocks the air outlet 330, and the panel 100 and the connecting rod 213 are both in the vertical direction. When the upper swing arm 211 swings to the upper limit position, the panel 100 has a certain angle with the vertical direction, and the upper part of the panel 100 is open outward, and the lower end of the panel 100 is lifted upward at least to the upper edge of the air outlet 330 to remove the obstruction of the air outlet 330.

[0055] It should be noted that, in this embodiment, an air inlet is provided at the top of the middle frame 300. When the panel 100 rises to the extreme position, the gap between the upper end of the panel 100 and the middle frame 300 reaches the maximum, which also makes the air inlet range wider and increases the air intake volume.

[0056] In this embodiment, a connecting pin 215 is provided at the end of the upper swing rod 211, and a connecting sleeve 217 matched with the connecting pin 215 is provided at the top end of the connecting rod 213, so that the upper swing rod 211 is hinged with the connecting rod 213. Specifically, the connecting pin 215 includes two interval-arranged inferior arc columns 215a, the two inferior arc columns 215a are inserted into the connecting sleeve 217, and the outer side surfaces of the two inferior arc columns 215a are arranged along the same circumferential surface, and an outward expansion stopper 215b is provided on the outer side surface of each inferior arc column 215a, and the two outward expansion stopper pieces 215b extend in a direction away from each other, and are used to be clamped on the connecting sleeve 217 to prevent the two inferior arc columns 215a from detaching from the connecting sleeve 217.

[0057] During actual assembly, one end face of the connecting sleeve 217 squeezes the two outward-expanding stop pieces 215b inward respectively, so that the two inferior arc bow columns 215a are brought closer to each other and reduced in diameter to be inserted into the connecting sleeve 217. After being inserted into place, the two inferior arc bow columns 215a restore the spacing. At this time, the two outward-expanding stop pieces 215b are abutted against the other end face of the connecting sleeve 217 to complete the assembly action.

[0058] See also Figure 6 and Figure 7 The connecting rod 213 is provided with a first clamping structure 218, and the panel 100 is provided with a second clamping structure 219. The first clamping structure 218 and the second clamping structure 219 are engaged with each other, so that the connecting rod 213 and the panel 100 are clamped together. Specifically, the connecting rod 213 and the panel 100 are clamped together, and the panel 100 and the connecting rod 213 are separately provided, and the connecting rod 213 and the panel 100 are clamped together, which facilitates the assembly and disassembly of the panel 100, and also enables the connecting rod 213 and the panel 100 to be manufactured separately, thereby reducing the manufacturing difficulty.

[0059] The first clamping structure 218 includes a matching buckle 218a and a matching slot 218b arranged on the upper and lower sides of the matching buckle 218a, and the second clamping structure 219 includes a positioning protrusion 219a and a positioning hook 219b arranged on the upper and lower sides of the positioning protrusion 219a. The matching buckle 218a is clamped on the positioning protrusion 219a, and the positioning hook 219b is assembled in the matching slot 218b. Through the clamping effect of the matching buckle 218a and the positioning protrusion 219a, the positioning hook 219b is assembled in the matching slot 218b at the same time, so that the connecting rod 213 and the panel 100 can be clamped in place, and the fixing effect is good, ensuring the integrity of the connecting rod 213 and the panel 100 during the movement process.

[0060] In this embodiment, the bottom of the matching buckle 218a has a first stop surface, and the top of the positioning protrusion 219a has a second stop surface. The first stop surface and the second stop surface are engaged, so that the matching buckle 218a and the positioning protrusion 219a are mutually clamped, so that the mounting seat 250 can limit the panel 100 downwards to prevent the panel 100 from loosening upwards relative to the mounting seat 250. At the same time, the positioning hook 219b is pressed on the bottom wall of the matching groove 218b and buckled on the side surface of the connecting rod 213 away from the panel 100, so that the positioning hook 219b and the bottom wall of the matching clamping are also mutually limited, and then the mounting seat 250 can limit the panel 100 upwards to prevent the panel 100 from loosening downwards relative to the mounting seat 250. Through the two-way limiting action of the matching groove and the matching buckle 218a, the panel 100 and the connecting rod 213 can be clamped into one body to prevent the panel 100 from loosening during the movement of the panel 100.

[0061] In this embodiment, the two mating slots 218b are both wide at the top and narrow at the bottom, that is, the width of the upper section of the mating slot 218b is greater than the width of the lower section, and the width of the lower section matches the width of the positioning hook 219b. During installation, the positioning hook 219b is first installed into the upper section of the mating slot 218b, and then pressed downward, so that the positioning hook 219b can be quickly inserted into the mating slot 218b.

[0062] See also Figure 8 and Fig. 9 The transmission connecting rod 210 further includes a slide bar 216, one end of which is connected to the bottom end of the connecting rod 213, and a slide groove 251 extending in the up-down direction is provided on the mounting seat 250, and the other end of the slide bar 216 extends into the slide groove 251 and can slide along the slide groove 251, so as to limit the connecting rod 213. By providing the slide bar 216 and extending the slide bar 216 into the slide groove 251, the slide bar 216 is limited by the slide groove 251, so as to achieve the limiting effect on the connecting rod 213 and the panel 100 in the left-right direction, thereby preventing the panel 100 from shaking left-right during the lifting process, and improving the stability of the panel 100.

[0063] In this embodiment, a stopper 216a is further provided at one end of the slide bar 216 away from the connecting rod 213, and the width of the stopper 216a is greater than the width of the slide groove 251 to prevent the slide bar 216 from escaping from the slide groove 251. By providing the stopper 216a at the end of the slide bar 216, the slide bar 216 can be prevented from escaping from the slide groove 251, thereby limiting the connecting rod 213 and the panel 100 in the front-to-back direction, preventing the panel 100 from shaking back and forth during the lifting process, and further improving the stability of the panel 100.

[0064] In this embodiment, two spaced stop bars 253 are provided on the mounting seat 250, a slide groove 251 is formed between the two stop bars 253, the stop block 216a is slidably abutted on the stop bar 253, and each stop bar 253 is arc-shaped, and the convex side of each stop bar 253 is close to the connecting rod 213. The slide groove 251 is formed by the two stop bars 253, and the stop block 216a is slidably abutted on the stop bar 253, and each stop bar 253 is arc-shaped, and the convex side of each stop bar 253 is close to the connecting rod 213, so that during the movement of the panel 100, the stop block 216a follows the panel 100 to make an arc movement and always abuts on the slide groove 251, further improving the stability of the panel 100 during the movement.

[0065] It should be noted that in this embodiment, the width of the groove between the two stopper bars 253 is greater than the width of the slide bar 216 and less than the width of the stopper block 216a. The arc-shaped structure of the stopper bar 253 enables the panel 100 to deflect outward for a distance during the rising process, thereby preventing the upper swing rod 211 from being locked.

[0066] See also Fig.10 and Fig.11 The lifting drive assembly 230 includes a gear seat 231, a driving member 233, a first transmission gear 235 and a second transmission gear 237. The gear seat 231 is arranged on the mounting seat 250, the driving member 233 is arranged on the gear seat 231, the first transmission gear 235 and the second transmission gear 237 are rotatably arranged in the gear seat 231 and mesh with each other, the first transmission gear 235 is connected to the driving member 233, and the second transmission gear 237 is connected to the transmission connecting rod 210. Specifically, the upper swing rod 211 extends into the gear second transmission gear 237 and is connected to the upper swing rod 211. The transmission of power is achieved through the gear meshing action of the first transmission gear 235 and the second transmission gear 237, which is stable and reliable.

[0067] In this embodiment, the driving member 233 is a stepper motor, and the output shaft of the motor is directly connected to the first transmission gear 235, thereby driving the first transmission gear 235 to rotate. Of course, the driving member 233 here can also be other types of rotation driving devices, such as a micro hydraulic motor, etc., which are not specifically limited here. Specifically, the stepper motor is accommodated in a driving box cover, and the driving box cover is fixed to the gear seat 231 by screws, and the output shaft of the stepper motor is connected to the first transmission gear 235 shaft in a transmission manner.

[0068] It should be noted that, in this embodiment, the rotation radius of the first transmission gear 235 is smaller than the rotation radius of the second transmission gear 237 , so that the first transmission gear 235 and the second transmission gear 237 form a deceleration structure to prevent the upper swing rod 211 from swinging quickly.

[0069] The gear seat 231 includes a gear cover 231a and a bottom plate 231b integrally provided with the mounting seat 250.
