[0002] The panel of the air conditioner is connected to the middle frame through the connecting bracket, and the panel is covered in front of the indoor unit body. Generally, the panel remains closed during the use of the air conditioner. When the heat exchanger needs to be maintained, the panel is opened, and the opening process is relatively complicated. In addition, this panel installation structure affects the air intake of the indoor unit to a certain extent, thereby affecting the working efficiency of the air conditioner.

When the motor drives the connecting rod to rotate upward, the panel leaves the front surface of the indoor unit body. Although this panel driving structure increases the air intake of the indoor unit to a certain extent, during the process of the motor driving the panel to open and close, due to the large gravity of the panel itself, the motor is subjected to large force, and large vibration is generated during the process of the panel opening and closing, which affects the service life of the motor and the air conditioner. Summary of the invention

[0004] In view of this, the present invention aims to provide a panel driving structure and an air conditioner to solve the problems in the prior art that the panel operates unstably during the opening and closing process and that the motor is subjected to greater force due to the greater gravity of the panel itself.

[0032] 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.

[0033] like Figures 1 to 11 As shown, this embodiment provides a panel driving structure for driving the opening and closing of the panel 2. The panel driving structure includes the panel 2, a driving device 1 and a middle frame 3, the driving device 1 is installed in the middle frame 3, the panel 2 covers the front side of the middle frame 3, and the driving device 1 drives the panel to open or close.

[0034] The driving device 1 includes a power bracket 11, a support 12 and a motor. A accommodating chamber 121 is arranged inside the support 12. One end of the power bracket 11 is installed on the support 12 through a mounting shaft 13. The other end of the power bracket 11 is connected to the panel 2. A gear structure is arranged on the mounting shaft 13. The motor drives the mounting shaft 13 to rotate through gear transmission, so that the mounting shaft 13 drives the power bracket 11 to rotate, so that the driving device 1 drives the panel 2 to open or close.

[0035] An elastic member 14 is installed on the installation shaft 13 or the power bracket 11, one end of the elastic member 14 is fixed on the support 12, and the other end is connected to the power bracket 11 and / or the installation shaft 13. When the panel 2 is closed, the support 12 remains stationary, and the motor drives the power bracket 11 and the installation shaft 13 to rotate, driving the position of one end of the elastic member 14 to change, and due to the effect of the gravity of the panel 2 itself, the elastic member 14 is deformed, and part of the energy is stored in the elastic member 14; when the panel 2 is opened, the elastic member 14 releases energy, and at the same time drives the installation shaft 13 and the power bracket 11 to rotate through the motor, so that the panel 2 is in an open state.

[0036] Furthermore, the motor is configured as a reduction motor to save electricity.

[0037] The panel driving structure provided in this embodiment installs an elastic member 14 on the mounting shaft 13, so that when the panel 2 is in a closed state, part of the energy is stored in the elastic member 14. When the panel 2 moves upward to open, the elastic member 14 gradually releases the energy, thereby reducing the force on the motor and reducing the vibration generated by the motor, thereby avoiding shaking of the panel 2 during the opening and closing process, improving the stability of the panel 2, and increasing the service life of the motor.

[0038] like Figure 3 , Figure 7 and Fig. 9 As shown, as part of an embodiment of the present invention, a limiting structure 114 is provided on the power bracket 11, and a limiting block 123 cooperating with the limiting structure 114 is provided on the support 12. The limiting structure 114 and the limiting block 123 cooperate to limit the rotation angle of the power bracket 11. When it is necessary to open the panel 2, the limiting structure 114 and the limiting block 123 cooperate to prevent the power bracket 11 from rotating further, so that the panel 2 is stabilized in the open state, thereby ensuring the stability of the air conditioner operation.

[0039] like Figures 5-6 As shown, a tooth structure is provided on the installation shaft 13, and the tooth structure 132 cooperates with the gear of the motor, so that the motor drives the installation shaft 13 and the power bracket 11 to rotate through the gear transmission structure.

[0040] like Figure 4 and Fig.11As shown, further, in order to prevent the elastic member 14 from being separated from the support 12 when the elastic member 14 is deformed, a mounting hole 125 is provided on the support 12, and a limiting protrusion 126 is provided on the edge of the mounting hole 125. One end of the elastic member 14 passes through the mounting hole 125 and is hooked on the support 12, thereby increasing the connection stability between the elastic member and the support 12 and preventing the elastic member 14 from being separated from the support 12 when the elastic member 14 is deformed.

[0041] like Figures 3 to 10 As shown, the power bracket 11 is configured as a bending structure, so that the panel 2 can move in an arc shape from closed to open, that is, the panel 2 moves forward and upward when it is opened. The power bracket 11 includes a first connection end 111, a second connection end 112 and a bracket body 115. The second connection end 112 is installed on the support 12 through the installation shaft 13, and the power bracket 11 is driven by the motor to rotate around the installation shaft 13. When the panel 2 is in the open state, the first connection end 111 and the bracket body 115 are exposed to the outside of the support 12; when the panel 2 is in the closed state, the bracket body 115 is received in the accommodating cavity 121 inside the support 12.

[0042] Furthermore, a connecting shaft 113 is provided on the first connecting end 111 of the power bracket 11 , and the panel 2 is connected to the power bracket 11 via the connecting shaft 113 , thereby enabling the power bracket 11 to drive the panel 2 to open and close.

[0043] The mounting shaft 13 is installed on the second connection end 112 of the power bracket 11, and the mounting shaft 13 is perpendicular to the side of the power bracket 11. The power bracket 11 is connected to the motor through the mounting shaft 13, so that the motor drives the power bracket 11 to rotate, and then the power bracket 11 drives the panel 2 to move.

[0044] Furthermore, a limiting structure 114 is provided on the second connection end 112 of the power bracket 11 to prevent the limiting structure 114 from interfering with the normal rotation range of the power bracket 11. When the panel 2 needs to be opened, the limiting structure 114 cooperates with the limiting block 123 to prevent the power bracket 11 from further rotating, so that the panel 2 is stabilized in the open state, thereby ensuring the stability of the air conditioner operation.

[0045] Furthermore, the support 12 includes a rear baffle 122 , a first side baffle 128 and a second side baffle 129 , and a receiving chamber 121 is formed inside the space surrounded by the rear baffle 122 , the first side baffle 128 and the second side baffle 129 for receiving the power bracket 11 .

[0046] The first side baffle 128 is parallel to the second side baffle 129, and the rear baffle 122 connects the first side baffle 128 and the second side baffle 129 together, so that the interior of the accommodating cavity 121 is separated from other components. One end of the installation shaft 13 passes through the first side baffle 128, and the other end passes through the second side baffle 129 to prevent interference with other components during the process of the installation shaft 13 driving the power bracket 11 to rotate, thereby affecting the movement trajectory of the panel 2.

[0047] The rear baffle 122 forms the bottom plate of the accommodating cavity 121. The accommodating cavity 121 forms a structure similar to a right triangle. The connecting part between the power bracket 11 and the mounting shaft 13 is equivalent to the right-angled vertex of the right triangle. The rear baffle 122 forms the hypotenuse of the right triangle. When the panel 2 is in a closed state and the power bracket 11 is located inside the accommodating cavity 121, the power bracket 11 abuts against the inner side of the rear baffle 122. The rear baffle 122 is used to prevent the power bracket 11 from further rotating to ensure the position of the panel 2 in the closed state.

[0048] Furthermore, a connecting portion 127 is provided on the support 12 , and the support 12 is fixedly mounted on the middle frame 3 via the connecting portion 127 , so as to prevent the driving device 1 from loosening during the operation of the panel 2 , thereby improving the operation stability of the panel 2 .

[0049] Preferably, the connection portion 127 is disposed on the first side baffle 128 and / or the second side baffle 129 to avoid interfering with the rotation of the power bracket 11. More preferably, the connection portion 127 is disposed on the first side baffle 128 and the second side baffle 129 on the side facing the bending direction of the power bracket 11 to avoid the connection portion 127 from affecting the rotation of the power bracket 11 and provide an escape space for the rotation of the power bracket 11. The connection portion 127 can be set as a screw hole to increase the connection stability between the support 12 and the middle frame 3.

[0050] A limit stopper 123 is provided inside the support 12, and the limit stopper 123 is provided inside the accommodating cavity 121 to prevent the power bracket 11 from further rotating. Preferably, two limit stops 123 are provided, corresponding to the two ends of the limit structure 114, respectively, to prevent the power bracket 11 from rotating toward the side close to the connecting portion 127, and to prevent the power bracket 11 from deflecting.

[0051] As part of an embodiment of the present invention, a partition 124 is also provided on the support 12 at a position corresponding to the mounting shaft 13. The partition 124 is parallel to the second side baffle 129, and the partition 124 is wrapped around one end of the mounting shaft 13. A notch or an opening is provided on the edge of the partition 124, and the notch or the opening cooperates with the motor to increase the compactness of the cooperation between the support 12 and the motor.

[0052] like Figures 3 to 5 , Figures 7 to 9 and Fig.11 As shown, further, the mounting shaft 13 includes a first mounting end 131, a second mounting end 134 and a mounting body, the mounting body is mounted inside the second connecting end 112 of the power bracket 11, the first mounting end 131 extends outward through the first side baffle 128, the second mounting end 134 extends outward through the second side baffle 129, and the partition 124 covers the outer side of the first mounting end 131, thereby protecting the mounting shaft 13 and preventing the mounting shaft 13 from being interfered with by other components during operation.

[0053] The elastic member 14 is installed inside the first mounting end 131 of the mounting shaft 13, and a slit 133 is set on the first mounting end 131 at a position corresponding to the elastic member 14, and both ends of the elastic member 14 extend out of the slit 133, wherein one end of the elastic member 14 is hooked on the partition 124, and the other end of the elastic member 14 is fixed at the connecting part of the power bracket 11 and the mounting shaft 13, so that when the mounting shaft 13 drives the power bracket 11 to rotate, one end of the elastic member 14 is fixed and the other end rotates, thereby realizing the process of energy storage and release of the elastic member 14.

[0054] Furthermore, a mounting portion is provided on the partition 124, and the mounting portion is provided as a groove-shaped structure or a hole-shaped structure, one end of the elastic member 14 is hooked on the mounting portion for fixing, and the other end moves with the power bracket 11 and the mounting shaft 13. Preferably, the mounting portion is provided as a mounting hole 125, and one end of the elastic member 14 passes through the mounting hole 125 and is hooked on the partition 124 at the edge of the mounting hole 125, so that one end of the elastic member 14 is fixed to the partition 124. Preferably, a limiting protrusion 126 is also provided on the edge of the mounting hole 125, and the limiting protrusion 126 is provided in two numbers and is respectively located on both sides of the mounting hole 125, so that one end of the elastic member 14 is located between the two limiting protrusions 126, so as to prevent the elastic member 14 from being displaced or shaken during the process of being deformed by force, so as to avoid affecting the rotation trajectory of the power bracket 11, and improve the operation stability of the panel 2 during the opening and closing process.

[0055] Preferably, the elastic member 14 can be configured as a torsion spring, one end of which is fixed on the partition 124, and the other end rotates with the power bracket 11 and the mounting shaft 13. When the panel 2 is in a closed state, the power bracket 11 is located inside the accommodating cavity 121, and the torsion spring stores part of the energy; when the panel 2 needs to be opened, the torsion spring releases the energy, and at the same time the motor drives the power bracket 11 to rotate, effectively reducing the motor pressure.

[0056] Furthermore, a tooth structure 132 is provided on the first mounting end 131 of the mounting shaft 13. The tooth structure 132 is provided at a position corresponding to the notch or opening of the partition 124. The tooth structure 132 cooperates with the gear of the motor to realize that the motor drives the mounting shaft 13 to rotate. Preferably, the arc area formed by the tooth structure 132 on the first mounting end 131 is smaller than the circumference of the first mounting end 131, so that the motor can only drive the mounting shaft 13 to rotate within a range less than 360 degrees, which has a limiting effect on the rotation angle of the mounting shaft 13 and the power bracket 11, and cooperates with the limiting structure 114 and the rear baffle 122 to increase the stability of the panel 2 during the opening and closing process.

[0057] As part of the implementation of the present invention, this embodiment also provides an air conditioner, including the panel drive structure described above, and the panel drive structure is installed on the indoor unit, so that when the panel is opened, it can not only facilitate the cleaning of the heat exchanger, but also increase the air intake volume, thereby improving the service life of the air conditioner.

[0058] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
