Description

Technical field: The invention relates to a lifting motor for a kitchen cabinet. Background technology: Existing kitchen cabinet lifting motors generally include a motor, a worm, a worm wheel and a winding wheel located on both sides of the worm. The two winding wheels are connected to the left and right sides of the kitchen cabinet through their own wire ropes. The two winding wheels synchronously reel in the wire ropes to achieve the overall lifting of the kitchen cabinet. Because the wire ropes on the left and right sides of the lifting motor must be the same length, the installation accuracy requirements are high and the structure is complex. In addition, during the actual lifting process, it is easy to cause the kitchen cabinet to be uneven, such as the left side is higher and the right side is lower, or the right side is higher and the left side is lower, which affects the user experience. Summary of the invention: In order to overcome the problems of high precision requirements for steel wire rope installation and complex structure of existing kitchen cabinet lifting motors, an embodiment of the present invention provides a kitchen cabinet lifting motor with a simple structure.

The reversing transmission assembly comprises at least a first reversing transmission wheel and a second reversing transmission wheel. The axes of the first reversing transmission wheel and the second reversing transmission wheel are perpendicular to each other, and the second reversing transmission wheel has a power output end that can cooperate with an external power transmission rod. The motor drives the first reversing transmission wheel to rotate, and the first reversing transmission wheel drives the second reversing transmission wheel to rotate, thereby converting the longitudinal output force of the motor into a lateral output force of the power output end of the second reversing transmission wheel to drive the kitchen cabinet to move up and down.

[0005] The kitchen cabinet lifting motor of the embodiment of the present invention removes the traditional steel wire rope and winding wheel structure, and adopts a reversing transmission assembly composed of a first reversing transmission wheel and a second reversing transmission wheel to convert the longitudinal output force of the motor into a lateral output force of the power output end of the second reversing transmission wheel to drive the kitchen cabinet to move up and down, and the motor structure is simpler. In addition, the external power transmission rod can be directly matched with the power output end of the second reversing transmission wheel, and the installation and use are convenient and quick.
