DETAILED DESCRIPTION

[0026] 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.

[0027] First embodiment

[0028] Please refer to Figure 1 and Figure 2The embodiment of the present invention provides a panel lifting mechanism 100 for lifting or lowering a panel 150. The panel 150 can be lifted or lowered so that the air outlet 210 can be fully opened, thereby preventing the panel 150 from blocking the air outlet 210, increasing the air volume, and ensuring smooth air supply.

[0029] In this embodiment, the panel lifting mechanism 100 is applied to a wall-mounted air conditioner, which is provided with an air outlet 210. The panel lifting mechanism 100 can lift and open the air outlet 210 to avoid obstruction of the air outlet 210 and increase the air volume. The panel lifting mechanism 100 can also descend and close the air outlet 210 to prevent dust from entering and improve the aesthetics of the wall-mounted air conditioner.

[0030] Please refer to Figure 3 The panel lifting mechanism 100 includes a driving box 110, a driving motor 120, a rocking arm 130, a connecting rod 140, a panel 150, a transmission gear 160, a first limiting column 170 and a second limiting column 180. The driving motor 120 is fixedly mounted on the driving box 110 and connected to the rocking arm 130. The driving motor 120 can drive the rocking arm 130 to rotate. The driving box 110 is provided with a slide groove 111. The connecting rod 140 is connected to the panel 150. One end of the connecting rod 140 is hinged to the rocking arm 130, and the other end is slidably arranged in the slide groove 111. The driving motor 120 can drive the connecting rod 140 to slide relative to the slide groove 111 through the rocking arm 130, so as to lift or lower the panel 150. Specifically, when the driving motor 120 drives the rocker 130 to rotate, the rocker 130 drives the connecting rod 140 to move so that the connecting rod 140 slides relative to the slide groove 111. The slide groove 111 can limit the position and sliding direction of the connecting rod 140 to ensure that the panel 150 connected to the connecting rod 140 can rise to open the air outlet 210 or fall to close the air outlet 210.

[0031] It is worth noting that the driving motor 120 is connected to the rocker 130 through the transmission gear 160. The driving motor 120 is provided with an output shaft 121, and the transmission gear 160 is sleeved outside the output shaft 121 and fixedly connected to the output shaft 121. When the driving motor 120 is started, the output shaft 121 can drive the transmission gear 160 to rotate. The rocker 130 is provided with a linkage tooth portion 131, which is installed on the driving box 110 and can rotate relative to the driving box 110 and mesh with the transmission gear 160. The rotation of the transmission gear 160 can drive the linkage tooth portion 131 to rotate, thereby driving the rocker 130 to rotate. In this embodiment, the drive motor 120 drives the rocker 130 to rotate by gear transmission, but is not limited to this. In other embodiments, the drive motor 120 can also drive the rocker 130 to rotate by directly connecting the output shaft 121 to the rocker 130. The drive motor 120 can also drive the rocker 130 to rotate by belt transmission or chain transmission. The transmission method between the drive motor 120 and the rocker 130 is not specifically limited.

[0032] It should be noted that the first limit post 170 and the second limit post 180 are both fixedly connected to the drive box 110. The first limit post 170 is used to stop and limit the rocker 130 when the rocker 130 rotates to the first limit position, and the second limit post 180 is used to stop and limit the rocker 130 when the rocker 130 rotates to the second limit position, so that the rocker 130 can only rotate between the first limit position and the second limit position. Specifically, when the rocker 130 rotates to the first limit position, the panel 150 rises to the highest position, and the air outlet 210 is opened; when the rocker 130 rotates to the second limit position, the panel 150 drops to the lowest position, and the air outlet 210 is closed.

[0033] Please refer to Figure 4 and Figure 5 The connecting rod 140 includes a connecting rod body 141, a first hinge part 142 and a guide slide post 143. One end of the connecting rod body 141 is fixedly connected to the first hinge part 142, and the other end is fixedly connected to the guide slide post 143. In this embodiment, the first hinge part 142, the connecting rod body 141 and the guide slide post 143 are integrally formed to improve the connection strength. The connecting rod body 141 is detachably connected to the panel 150 for easy installation and maintenance. The rocker 130 is provided with a second hinge part 132, the first hinge part 142 is hinged to the second hinge part 132, and the first hinge part 142 can rotate relative to the second hinge part 132, so that the rocker 130 can drive the connecting rod body 141 to move while rotating. The guide slide post 143 extends into the slide groove 111 and can slide relative to the slide groove 111. The slide groove 111 can limit the sliding direction of the guide slide post 143, thereby limiting the movement direction of the connecting rod body 141.

[0034] It should be noted that a slot 144 is provided on the connecting rod body 141, and a buckle 151 is provided on the panel 150. The buckle 151 can be inserted into the slot 144 and cooperate with the slot 144 to fix the relative position of the connecting rod body 141 and the panel 150. In this embodiment, the slot 144 includes a first end wall 1441, a second end wall 1442 and two side walls 1443. One end of the first end wall 1441 is fixedly connected to one end of the second end wall 1442 through one side wall 1443, and the other end of the first end wall 1441 is fixedly connected to the other end of the second end wall 1442 through another side wall 1443. The two side walls 1443 are arranged opposite to each other, and the buckle 151 is arranged between the two side walls 1443, and the two side walls 1443 can limit the buckle 151. During the engagement process of the buckle 151 and the slot 144, the buckle 151 is first extended into the slot 144, and then the buckle 151 is moved from the first end wall 1441 toward the second end wall 1442 relative to the connecting rod body 141 until the buckle 151 abuts against the second end wall 1442, thereby achieving engagement of the buckle 151 and the slot 144.

[0035] Specifically, the side wall 1443 includes a first connection portion 1444, a guide portion 1445, and a second connection portion 1446. The first connection portion 1444 is fixedly connected to the first end wall 1441, the first connection portion 1444 is fixedly connected to the second connection portion 1446 through the guide portion 1445, the second connection portion 1446 is fixedly connected to the second end portion, the first connection portion 1444 and the second connection portion 1446 are arranged in parallel, the guide portion 1445 is inclined toward the other side wall 1443, and the guide portion 1445 is used to guide the buckle 151. Further, the length of the first end wall 1441 is greater than the length of the second end wall 1442, the spacing between the two first connection portions 1444 is greater than the spacing between the two second connection portions 1446, and the two guide portions 1445 gradually approach each other in the direction from the first end wall 1441 to the second end wall 1442. During the cooperation between the buckle 151 and the slot 144, the buckle 151 is first extended between the two first connecting parts 1444. Since the spacing between the two first connecting parts 1444 is large, the buckle 151 can be extended quickly and easily, and then the buckle 151 is moved from the first end wall 1441 to the second end wall 1442 relative to the connecting rod body 141. During this process, the two guide parts 1445 can guide the buckle 151 at the same time, so that the buckle 151 can quickly slide between the two second connecting parts 1446. Finally, the buckle 151 slides between the two second connecting parts 1446 until it abuts against the second end wall 1442. The two second connecting parts 1446 jointly limit the buckle 151, and the second end wall 1442 can prevent the buckle 151 from continuing to move from the first end wall 1441 to the second end wall 1442.

[0036] It should be noted that the connecting rod body 141 is provided with a spring buckle 145, and the panel 150 is provided with a top buckle 152, and the spring buckle 145 is engaged with the top buckle 152 to further fix the relative position of the connecting rod body 141 and the panel 150. In the process that the buckle 151 moves from the first end wall 1441 to the second end wall 1442 relative to the connecting rod body 141, the top buckle 152 abuts against the spring buckle 145 to lift the spring buckle 145 away from the panel 150. When the buckle 151 abuts against the second end wall 1442, the spring buckle 145 falls and is engaged with the top buckle 152, and the spring buckle 145 can prevent the top buckle 152 from moving in the direction from the second end wall 1442 to the first end wall 1441.

[0037] For ease of understanding, the direction from the first end wall 1441 to the second end wall 1442 is indicated as the first direction, and the direction from the second end wall 1442 to the first end wall 1441 is indicated as the second direction, and the first direction is opposite to the second direction. In this embodiment, when the connecting rod body 141 and the panel 150 are matched, the buckle 151 abuts against the second end wall 1442, and the second end wall 1442 can prevent the buckle 151 from continuing to move in the first direction, that is, prevent the panel 150 from moving relative to the connecting rod body 141 along the first direction; the spring buckle 145 is engaged with the top buckle 152, and the spring buckle 145 can prevent the top buckle 152 from moving in the second direction, that is, prevent the panel 150 from moving relative to the connecting rod body 141 along the second direction. The card slot 144 and the spring buckle 145 work together to limit the panel 150, thereby fixing the relative position of the connecting rod body 141 and the panel 150, which is convenient to operate, has a good fixing effect, and is easy to disassemble and assemble.

[0038] In this embodiment, there are two slots 144 and two buckles 151, and the two slots 144 are arranged at intervals along the length direction of the connecting rod 140, and each buckle 151 cooperates with one slot 144. Specifically, the spring buckle 145 is arranged between the two slots 144, and the top buckle 152 is arranged between the two buckles 151, so as to further improve the fixing effect of the connecting rod body 141 and the panel 150, and prevent the panel 150 from being separated from the connecting rod body 141.

[0039] In this embodiment, the first hinge part 142 is annular, the second hinge part 132 is columnar, the second hinge part 132 extends into the first hinge part 142, and can rotate relative to the first hinge part 142 to achieve the hinge connection between the connecting rod body 141 and the rocker 130. Specifically, the free end of the second hinge part 132 is provided with an anti-slip head (not shown), the cross-sectional area of ​​the anti-slip head is larger than the cross-sectional area of ​​the second hinge part 132, so as to prevent the second hinge part 132 from slipping out of the first hinge part 142. However, it is not limited to this. In other embodiments, the first hinge part 142 is columnar, the second hinge part 132 is annular, and the first hinge part 142 extends into the second hinge part 132, which can also achieve the hinge connection between the connecting rod body 141 and the rocker 130.

[0040] It is worth noting that a limiting head 146 is provided at one end of the guide slide post 143 away from the connecting rod body 141, and the cross-sectional area of ​​the limiting head 146 is larger than the cross-sectional area of ​​the guide slide post 143 to prevent the guide slide post 143 from being separated from the slide slot 111. In this embodiment, the slide slot 111 is arranged in an arc shape along its depth direction, and the shape of the slide slot 111 matches the motion trajectory of the second hinge part 132 of the rocker 130. The slide slot 111 can limit the guide slide post 143, and the second hinge part 132 can limit the first hinge part 142, so as to jointly limit the motion trajectory of the connecting rod 140, thereby limiting the motion trajectory of the panel 150, so that the panel 150 can rise to open the air outlet 210 or fall to close the air outlet 210.

[0041] Please refer to Figure 6 , Figure 7 and Figure 8 It should be noted that when the panel 150 rises to open the air outlet 210, the drive motor 120 drives the rocker 130 to rotate toward the first limit position through the transmission gear 160. During this process, the rocker 130 drives the connecting rod 140 to rise while rotating relative to the connecting rod 140, so that the guide slide column 143 of the connecting rod 140 slides upward in the slide groove 111 of the drive box 110, thereby driving the entire panel 150 to rise upward to open the air outlet 210. When the rocker 130 rotates to the first limit position, the rocker 130 abuts against the first limit column 170. At this time, the connecting rod 140 and the panel 150 both move to the upper limit position. When the panel 150 descends to close the air outlet 210, the drive motor 120 drives the rocker 130 to rotate toward the second extreme position through the transmission gear 160. During this process, the rocker 130 drives the connecting rod 140 to descend while rotating relative to the connecting rod 140, so that the guide slide column 143 of the connecting rod 140 slides downward in the slide groove 111 of the drive box 110, thereby driving the entire panel 150 to descend to close the air outlet 210. When the rocker 130 rotates to the second extreme position, the rocker 130 abuts against the second limit column 180. At this time, the connecting rod 140 and the panel 150 both move to the lower extreme position.

[0042] In the panel lifting mechanism 100 described in the embodiment of the present invention, the driving motor 120 is fixedly mounted on the driving box 110 and connected to the rocker 130. The driving box 110 is provided with a slide slot 111. The connecting rod 140 is connected to the panel 150. One end of the connecting rod 140 is hinged to the rocker 130, and the other end is slidably arranged in the slide slot 111. The driving motor 120 can drive the connecting rod 140 to slide relative to the slide slot 111 through the rocker 130, so as to raise or lower the panel 150. Compared with the prior art, the panel lifting mechanism 100 provided by the present invention adopts the driving motor 120 connected to the rocker 130 and the connecting rod 140 that can slide relative to the slide slot 111, so that the panel 150 can be lifted or lowered, so that the air outlet 210 can be fully opened, thereby avoiding the panel 150 from blocking the air outlet 210, increasing the air volume, and ensuring smooth air supply.
