[0024] In order to further understand the content, characteristics and effects of the present application, the following embodiments are exemplified and described in detail as follows with reference to the accompanying drawings:

[0025] Please refer to Figure 1 and Figure 2 , Figure 1 is a perspective view of a motor applied to a cabinet in an embodiment of the present application; Figure 2Another perspective view of the motor applied to the cabinet in the embodiment of the present application. As shown in the figure, the mounting shell 11, the driving motor 12, the speed reduction mechanism 13 and the clutch mechanism 14 of the present application. The driving motor 12 is arranged in the mounting shell 11. The speed reduction mechanism 13 is arranged in the mounting shell 11, and the speed reduction mechanism 13 is connected to the output end of the driving motor 12. The clutch mechanism 14 is arranged in the mounting shell 11, and the clutch mechanism 14 is connected to the driving motor 12 and the speed reduction mechanism 13 respectively. When the motor applied to the cabinet is powered on, the driving motor 12 generates driving force, the driving force is transmitted to the speed reduction mechanism 13 through the clutch mechanism 14, and the speed reduction mechanism 13 is output to the cabinet door after being decelerated, and the opening or closing of the cabinet door is realized by controlling the forward rotation or reverse rotation of the driving motor 12. When power failure occurs, the connection between the driving motor 12 and the speed reduction mechanism 13 is cut off through the clutch mechanism 14, so as to avoid damage to the driving motor 12 caused by manually opening or closing the cabinet door.

[0026] Further referring to Figure 3 , Figure 4 and Figure 5 , Figure 3 the structure diagram of the clutch mechanism 14 in the embodiment of the present application; Figure 4 the sectional view of the clutch mechanism 14 in the embodiment of the present application; Figure 5 the exploded view of the clutch mechanism 14 in the embodiment of the present application. As shown in the figure, the clutch mechanism 14 includes a clutch gear shaft 141, a clutch tooth plate 142, a clutch piece 143 and a clutch adjusting piece 144. The clutch gear shaft 141 is rotatably arranged in the mounting shell 11, and the gear of the clutch gear shaft 141 is engaged with the speed reduction mechanism 13. The clutch tooth plate 142 is sleeved on the clutch gear shaft 141. The clutch piece 143 is sleeved on the clutch gear shaft 141, and the clutch piece 143 is movably connected to the clutch tooth plate 142. The clutch adjusting piece 144 is arranged in the mounting shell 11, and the clutch adjusting piece 144 is connected to the clutch gear shaft 141. In specific application, the clutch tooth plate 142 has a convex part 1421, and the clutch piece 143 has a concave part 1431. By default, the convex part 1421 is inserted into the concave part 1431, so that when the driving motor 12 drives the clutch tooth plate 142 to rotate, the clutch tooth plate 142 drives the clutch piece 143 to rotate, and the clutch piece 143 drives the clutch gear shaft 141 to rotate, thereby driving the speed reduction mechanism 13 engaged with the clutch gear shaft 141 to rotate. When power failure occurs, only manual opening or closing of the cabinet door can be performed, the clutch adjusting piece 144 is pulled away from the clutch tooth plate 142, the clutch adjusting piece 144 drives the clutch gear shaft 141 and the clutch piece 143 to move away from the clutch tooth plate 142, so that the convex part 1421 is separated from the concave part 1431. In this way, when the cabinet door is opened or closed, the cabinet door drives the speed reduction mechanism 13 to rotate, and the speed reduction mechanism 13 only drives the clutch piece 143 to rotate, without driving the clutch tooth plate 142 to rotate, thereby avoiding that the rotation of the clutch tooth plate 142 forcibly drives the driving motor 12 to rotate, which causes damage to the driving motor 12.

[0027] Preferably, the clutch mechanism 14 further comprises a resilient member 145, which is a spring. The resilient member 145 is sleeved on the clutch gear shaft 141, and the two ends of the resilient member 145 abut against the clutch tooth plate 142 and the clutch plate 143 respectively. In this embodiment, after the resilient member 145 is added to the clutch mechanism 14, the clutch adjusting member 144 is not connected with the clutch gear shaft 141, but is screwed on the mounting shell 11. One end of the clutch adjusting member 144 abuts against one end of the clutch gear shaft 141. By default, the resilient member 145 is in a compressed state. When the power is off and the cabinet door needs to be opened or closed, the clutch adjusting member 144 is screwed, and the clutch adjusting member 144 moves away from the clutch tooth plate 142. The resilient member 145 restores to the uncompressed state, and the elastic force of the resilient member 145 pushes the clutch plate 143 to move away from the clutch tooth plate 142, so that the convex part 1421 is separated from the concave part 1431, and the clutch tooth plate 142 no longer rotates synchronously with the clutch plate 143.

[0028] Preferably, the clutch mechanism 14 further comprises a bearing 146. The bearing 146 is sleeved on the two ends of the clutch gear shaft 141 respectively. The bearing 146 supports the clutch gear shaft 141, reduces the friction coefficient during movement, and ensures the rotation accuracy.

[0029] Preferably, the clutch gear shaft 141 has a spline 1411, and the clutch plate 143 is sleeved on the spline 1411. The spline 1411 enhances the connection reliability between the clutch gear shaft 141 and the clutch plate 143, and ensures that the clutch plate 143 and the clutch gear shaft 141 always rotate synchronously.

[0030] Preferably, the clutch adjusting member 144 has a convex pattern 1441. The convex pattern 1441 increases the friction force, and facilitates screwing of the clutch adjusting member 144.

[0031] Referring back to Figure 2 , the speed reduction mechanism 13 comprises a first speed reduction gear 131, a second speed reduction gear 132 and a third speed reduction gear 133. The first speed reduction gear 131 is rotationally arranged on the mounting shell 11, and the first speed reduction gear 131 is meshed with the gear on the clutch gear shaft 141 of the clutch mechanism 14. The second speed reduction gear 132 is rotationally arranged on the mounting shell 11, and the second speed reduction gear 132 is meshed with the first speed reduction gear 131. The third speed reduction gear 133 is rotationally arranged on the mounting shell 11, and the third speed reduction gear is meshed with the second speed reduction gear 132. The first speed reduction gear 131, the second speed reduction gear 132 and the third speed reduction gear 133 of the speed reduction mechanism 13 respectively reduce the speed to ensure the output torque.

[0032] In specific applications, the motor applied to the cabinet of the present application further comprises a motor shaft limiting mechanism 15; the motor shaft limiting mechanism 15 is arranged on the mounting shell 11. Referring back to Figure 6 ,Figure 6 Fig. 8 is a schematic view of the motor shaft limiting mechanism 15 according to an embodiment of the present application. As shown in the figure, the motor shaft limiting mechanism 15 comprises a limiting plate 151 and a limiting member 152. The limiting plate 151 is arranged on the mounting shell 11. The limiting member 152 is arranged on the limiting plate 151, and the output shaft of the driving motor 12 is inserted into the limiting member 152 away from the driving motor 12. In this embodiment, the limiting member 152 is an oil-containing bearing, which supports and limits the output shaft of the driving motor 12 and ensures the rotation of the output shaft, thus being convenient to use. Of course, the limiting member 152 can also be other components, and the above is only one embodiment of the present application, which should not be limited thereto.

[0033] In a specific application, the limiting plate 151 has a limiting groove 1511, and the limiting member 152 is arranged in the limiting groove 1511. By arranging the limiting groove 1511 on the limiting plate 151, the limiting member 152 can be conveniently installed and removed. Preferably, a gasket 15111 is arranged in the limiting groove 1511, one side of the gasket 15111 abuts against the inner side wall of the limiting groove 1511, and the other side of the gasket 15111 abuts against the limiting member 152. The gasket 15111 buffers the limiting member 152 to eliminate the noise caused by the movement and improve the wear resistance.

[0034] In a specific application, a worm 121 is arranged on the output shaft of the driving motor 12, the worm 121 is connected to the clutch tooth piece 142 of the clutch mechanism 14 through a connecting gear, the driving force generated by the driving motor 12 is transmitted to the clutch mechanism 14 through the worm 121, and then transmitted to the cabinet door through the speed reduction mechanism 13 to drive the cabinet door to open and close.

[0035] In summary, in one or more embodiments of the present application, the motor structure applied to the cabinet is simple, the clutch mechanism is additionally arranged, the connection between the driving motor and the speed reduction mechanism can be cut off in the case of power failure, and then the cabinet door can be manually opened and closed, which avoids the damage to the motor caused by forcibly opening and closing the cabinet door, is high in reliability, and effectively improves the service life of the product.

[0036] The above merely describes the embodiments of the present application and should not be used to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
