[0034] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, the present invention provides a preferred embodiment of a driving device for an air conditioner front panel.

[0036] A driving device 300 for an air conditioner front panel 200, the air conditioner including a middle frame 100 and a front panel 200 movable on a front end surface 101 of the middle frame 100, the driving device 300 including a lifting mechanism 310 connected to the front end surface 101 of the middle frame 100 and a front-and-rear moving mechanism connected to the lifting mechanism 310 and the front panel 200, respectively, the lifting mechanism 310 drives the front-and-rear moving mechanism and the front panel 200 to move up and down, the front-and-rear moving mechanism passively adjusting the front-and-rear position of the front panel 200 as the lifting mechanism 310 moves up and down, or the front-and-rear moving mechanism actively adjusting the front-and-rear position of the front panel 200.

[0037] Among them, the front end surface 101 of the middle frame 100 is provided with a first air outlet 110, and the first air outlet 110 is an opening provided on the middle frame 100 to blow out air. The front panel 200 can be movably provided on the front end surface 101 of the middle frame 100, forming a system resistance for blowing out air from the first air outlet 110. Driven by the driving device 300, when the front panel 200 moves back and forth relative to the front end surface 101, even if the front panel 200 is away from or close to the front end surface 101 of the air conditioner, the front panel 200 and the front end surface 101 form a resistance to the first air outlet 110. 0 connected to the air outlet channel 10, which is equivalent to the gap space formed between the front panel 200 and the front face 101. The air outlet channel 10 forms at least one second air outlet at the edge of the front panel 200, which is equivalent to the edge opening of the gap space. The wind blown out of the first air outlet 110 is partially blocked by the front panel 200, enters the air outlet channel 10, and is then directed to the second air outlet for blowing out, achieving a controllable soft wind state. The wind speed is controlled by the front panel 200, which reduces the changes in the internal structure, reduces R&D and product costs, and has strong controllability. Driven by the drive device 300, the panel can move forward and backward relative to the front face 101 to adjust the size of the air outlet channel 10 to control the air intake of the air outlet channel 10. The change trend of the space size and the air intake is in the same direction. In addition, the front panel 200 can also move up and down relative to the front face 101 to adjust the opening and closing of the first air outlet 110 to control the air intake of the air outlet channel 10. The opening and closing degree and the change trend of the air intake are opposite.

[0038] The specific working method of the driving device 300 is as follows: the lifting mechanism 310 drives the front-to-back moving mechanism to move up and down, and the front-to-back moving mechanism drives the front panel 200 to move up and down. At the same time, during the lifting process or when the lifting is stationary, the front-to-back moving mechanism also drives the front panel 200 to move back and forth. If the front-to-back moving mechanism is a passive structure and needs to cooperate with the lifting process to achieve back-to-back movement, during the process of the lifting mechanism 310 driving the front-to-back moving mechanism to move up and down, at least part of the process simultaneously drives the front panel 200 to move back and forth. If the front-to-back moving mechanism is an active structure, regardless of whether it is lifting or stationary, the front-to-back moving mechanism actively drives the front panel 200 to move back and forth.

[0039] like Figures 3 to 9 As shown, the present invention provides a preferred embodiment of the forward and backward moving mechanism.

[0040] The front-to-back movement mechanism is essentially used to adjust the front-to-back position of the front panel 200 relative to the middle frame 100, and multiple solutions are provided.

[0041] Solution 1: Reference Figure 3 As shown in the figure, the front-back moving mechanism includes a connecting rod 331, and the driving device 300 also includes a track block 332 fixed on the middle frame 100 and provided with a track 3321. The two ends of the connecting rod 331 are respectively connected to the lifting mechanism 310 and the front panel 200, and its mounting portion is slidably connected to the track 3321. The connecting rod 331 adjusts the front end of the connecting rod along the track of the track 3321 under the lifting and lowering drive of the lifting mechanism 310 to control the front and rear position of the front panel 200 during the lifting process.

[0042] Furthermore, the track 3321 is a track 3321 groove disposed on one end surface of the track block 332. A hole 321 or a rotating shaft is disposed on one end surface of the front panel 200. The mounting portion of the connecting rod 331 comprises a first protrusion 3312 that slidably engages with the track 3321 groove. A second protrusion 3313 or a hole is disposed at its front end, engaging with the hole 321 or the rotating shaft of the front panel 200. The first and second protrusions 3312 and 3313, or the first protrusion 3312 and hole, of the connecting rod 331 are disposed on both end surfaces, respectively. Preferably, the track 3321 of the track block 332 is in the shape of a multi-segment line, preferably a vertical upper portion and a curved lower portion.

[0043] Specifically, when the lifting end 312 of the lifting mechanism 310 rises, it drives the rear end of the connecting rod 331 upward. Driven by the rising rear end of the connecting rod 331, the connecting rod 331 moves along the track 3321, such as along a curved track, which causes the connecting rod 331 to tilt and move its front end forward. Then, the connecting rod 331 moves along a vertical track, driving the connected front end upward, thereby driving the front panel 200 forward and upward. Of course, in order to provide the connecting rod 331 with space for forward and backward movement, a vertical rotation limiter structure is required to achieve two-level limiter positions. That is, when the lifting end 312 of the lifting mechanism 310 rises, it drives the rear end of the connecting rod 331 upward, while simultaneously causing the entire connecting rod 331 to abut against the lower limiter position, thereby limiting the distance of forward movement. Therefore, the rear end of the connecting rod 331 is rotationally connected to the shaft 3121 of the lifting end 312 of the lifting mechanism 310 via the space 3311.

[0044] Option 2, Reference Figure 5The front-to-back moving mechanism includes a connecting rod 341 and a first driving motor 342 arranged on the lifting end 312 of the lifting mechanism 310. The two ends of the connecting rod 341 are respectively connected to the first driving motor 342 and the front panel 200. The rear end of the driving connecting rod 341 of the first driving motor 342 rotates to adjust the front-to-back position of the front end of the connecting rod 341 to control the front-to-back position of the front panel 200.

[0045] The first drive motor 342 drives the rear end of the connecting rod 341 to move relatively upward or downward. Since the first drive motor 342 drives the connecting rod 341 in a rotational manner, an offset phenomenon occurs, thereby adjusting the cutting angle of the connecting rod 341, thereby causing the front end of the connecting rod 341 to move back and forth, thereby controlling the front and rear position of the front panel 200. Specifically, a turntable is provided extending from the first drive motor 342, and the rear end of the connecting rod 341 is rotatably connected to a non-center position 3411 of the turntable. The first drive motor 342 drives the turntable to rotate about the center position and drives the connecting rod 341 to tilt. The rotation of the turntable causes the rear end of the connecting rod 341 to move back and forth relative to the lifting end 312 of the lifting mechanism 310. At the same time, the change in the tilt of the connecting rod 341 further causes the front end of the connecting rod 341 to move back and forth relative to the lifting end 312 of the lifting mechanism 310.

[0046] Option 3: Reference Figure 6 The front-to-back moving mechanism includes a connecting rod 351 and a first limiting structure 352 arranged on the fixed end 311 of the lifting mechanism 310. The two ends of the connecting rod 351 are respectively connected to the lifting mechanism 310 and the front panel 200. The limiting portion of the first limiting structure 352 is clamped at the lower end of the connecting rod 351. The connecting rod 351 cooperates with the limiting portion to produce a corresponding angular rotation under the lifting drive of the lifting mechanism 310, adjusting the front-to-back position of the front end of the connecting rod 351 to control the front-to-back position of the front panel 200 during the lifting process.

[0047] The core of the solution is similar to Solution 1, which mainly replaces the track block 332 with the first limiting structure 352, so that during the rising process of the rear end of the connecting rod 351, the connecting rod 351 is tilted through the action of the front end gravity and the clamping action of the middle limiting part, thereby realizing the forward and backward movement of the rear end of the connecting rod 351.

[0048] Option 4: Reference Figure 7The front-to-back movement mechanism includes a connecting rod 361 and a movable top rod 3621. The movable top rod 3621 is connected to the fixed end 311 of the lifting mechanism 310 through a spring 3622, and is also rotatably connected to the mounting portion of the connecting rod 361. The two ends of the connecting rod 361 are respectively connected to the lifting mechanism 310 and the front panel 200. The connecting rod 361 rotates with the movable top rod 3621 under the lifting and lowering drive of the lifting mechanism 310, and the front-to-back position of the front end of the connecting rod 361 is adjusted by rotating around the rotating connection with the movable top rod 3621 to control the front-to-back position of the front panel 200 during the lifting process.

[0049] The support point of the connecting rod 361 is formed by the movable top rod 3621, so that the connecting rod 361 tilts during the rising process, and the spring 3622 is set on the movable top rod 3621 to slow down the impact of the movement of the connecting rod 361, so that the front end of the connecting rod 361 can move forward to different degrees during the rising process, so as to meet the movement requirements of the front panel 200 under different requirements.

[0050] Option 5: Reference Figure 8 The front-to-back moving mechanism includes a second driving motor 371 arranged at the lifting end 312 of the lifting mechanism 310 and a guide rack 372 connected to the front panel 200. The second driving motor 371 is provided with a second rotating gear 3711 engaged with the guide rack 372 to adjust the front-to-back position of the front panel 200.

[0051] This solution is similar to Solution 2. By installing a second drive motor 371 and other supporting guide structures at the lifting end 312 of the lifting mechanism 310, the front panel 200 can move forward and backward relative to the lifting mechanism 310. Specifically, the guide structures involve the second drive motor 371 driving a second rotating gear 3711, thereby driving a horizontally mounted guide rack 372 forward and backward. Furthermore, a guide rod 3731 and a guide sleeve 3732 are provided at either the upper or lower position to provide auxiliary guidance for horizontal movement.

[0052] In this embodiment, the front-rear moving mechanism is provided with at least two connecting rods, and at least two connecting rods are arranged at upper and lower positions, thereby improving the stability of the front panel 200 relative to the lifting mechanism 310.

[0053] refer to Figures 1 to 8 The driving device 300 also includes a support frame 320 connected to the front-back moving mechanism, and the front-back moving mechanism is connected to the front panel 200 through the support frame 320 to drive the support frame 320 to move, thereby driving the front panel 200 to move.

[0054] Specifically, the front panel 200 in solutions 1 to 5 is replaced with a support frame 320 . The support frame 320 is directly fixed to the front panel 200 and serves as an intermediate conversion component to improve the installation convenience of the front panel 200 .

[0055] like Figure 9 and Figure 10 As shown, the present invention provides a preferred embodiment of the lifting mechanism.

[0056] The lifting mechanism 310 includes a mounting plate as a fixed end 311 and a slider as a lifting end 312. A third drive motor 410 is provided on the mounting plate, and a first rotating gear 420 is provided on the third drive motor 410. The slider is provided with a rack 3122 that engages with the first rotating gear 420.

[0057] Specifically, the slider is mounted on a mounting plate and can slide up and down. The third drive motor 410 drives the first rotating gear 420 to rotate, which cooperates with the rack 3122 disposed in the vertical direction of the slider to drive the slider up and down. Furthermore, a slide groove and a slide rail are respectively disposed between the mounting plate and the slider to facilitate stable up and down movement of the slider on the mounting plate. For example, a raised slide rail 3111 is disposed on the mounting plate, and a groove 3124 is disposed on the slider that can be sleeved onto the raised slide rail 3111. Preferably, the mounting plate and the slider are arranged in a front-to-back direction, the first rotating gear 420 of the third drive motor 410 is disposed toward the slider, and the teeth of the slider rack 3122 face left or right, cooperating with the rotation direction of the first rotating gear 420, thereby achieving controllable sliding of the slider on the mounting plate.

[0058] In this embodiment, the slider is provided with a second limiting structure 3123. This second limiting structure 3123 is a limiting groove that forms an upper limit edge and a lower limit edge. The connecting rod is rotatably mounted in the limiting groove and swings up and down between the upper and lower limit edges around a rotation axis. Specifically, the second limiting structure 3123 is a triangular-shaped limiting groove with a narrow rear end and a front frame. The rear end of the connecting rod is rotatably mounted on a rotating axis at the rear end of the limiting groove and can swing up and down within the limiting groove until it abuts against the upper or lower limit edge, thereby limiting the inclination angle of the connecting rod and increasing the upward support force of the front end of the connecting rod to support the front panel 200.

[0059] In this embodiment, an elastic member 322 is provided at the bottom of the front panel 200. When unpressurized, the elastic member 322 protrudes from the bottom of the front panel 200 and presses back into the front panel 200 when pressurized. The elastic member 322 provides a cushioning force when the front panel 200 descends to its lowest position, improving the stability of the entire structure and preventing damage from a hard landing. Specifically, a groove is provided at the bottom of the front panel 200. The elastic member 322 includes a support member and a spring structure. The support member is positioned at the bottom of the groove via the spring structure. When the spring structure is functioning properly, the elastic member 322 protrudes from the groove under its own weight and can be accommodated within the groove.

[0060] like Figure 1 and Figure 2 As shown, the present invention provides a preferred embodiment of the air conditioner.

[0061] An air conditioner includes a middle frame 100 and a front panel 200 movable on a front end surface 101 of the middle frame 100. The air conditioner also includes a drive device 300, at least one of which is disposed on the front end surface 101 of the middle frame 100. Mounting plates of the drive device 300 are fixed to both sides of the front end surface 101 of the middle frame 100, and are fixed to both sides of the front panel 200, respectively, to ensure that the front panel 200 can move stably on the middle frame 100.

[0062] For example, through solution 1, the front panel 200 moves forward and backward, away from or closer to the front face 101. Moreover, when the front panel 200 moves from the horizontal direction to the position farthest from the front face 101, it continues to move along the vertical motion trajectory, thereby achieving the front panel 200 moving forward and backward relative to the front face 101 and the front panel 200 moving up and down relative to the front face 101.

[0063] The above description is only the best embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes or modifications made according to the scope of the patent application of the present invention are covered by the present invention.
