When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 to 2 show the platform lifting mechanism of the present invention, which comprises a base 10, a platform 20 and two driving assemblies 30.

The base 10 includes a main body 11 and two slide rails 12. The body 11 is U-shaped. The two slide rails 12 extend from the inner walls of the main body 11.

The platform 20 includes a beam 21, two connecting blocks 22, and two rollers 23. Two connecting blocks 22 extend from two ends of the beam 21. The two connecting blocks 22 are parallel to each other. Each connecting block 22 is perpendicular to the cross beam 21. The two rollers 23 are rotatably mounted on the two connecting blocks 22, respectively. The platform 20 is generally inverted U-shaped.

Each driving assembly 30 includes a driving member 31, a cam 32, an elastic member 33, a sliding block 34, and a contact wheel 35. The drive member 31 is a motor. The cam 32 is an eccentric. The elastic member 33 is a spring. The slide block 34 is provided with a ramp 340.

When the platform elevating mechanism is assembled, the connecting block 22 of the platform 20 is slidably connected with the main body 11 of the base 10. The driving member 31 is fixedly mounted on a side plate of the main body 11. The cam 32 is fixedly mounted to the output wheel of the driver 31. The slide block 34 is slidably mounted to the slide rail 12. Contact wheel 35 is rotatably mounted at the end of slide block 34. The elastic member 33 has one end fixed to the body 11 and the other end fixed to the slide block 34. The elastic member 33 keeps the contact wheel 35 on the slide block 34 in close contact with the cam 32. The contact wheel 35 brings the slide block 34 into rolling contact with the cam 32, reducing friction. The inclined surface 340 on the sliding block 34 contacts with the roller 23, and the sliding block 34 rolls and contacts with the platform 20, so that friction is reduced.

When the platform lifting mechanism is used, the driving members 31 of the two driving assemblies 30 work simultaneously, the output shaft of the driving member 31 drives the cam 32 to rotate, and the cam 32 is an eccentric wheel, so that the cam 32 contacts the contact wheel 35 in the rotating process, and the sliding block 34 moves transversely and reciprocally relative to the base 10. Since the inclined surface 340 is in contact with the roller 23, the slide block 34 reciprocates the platform 20 up and down during the lateral reciprocating movement. The direction of movement of the slider 34 is perpendicular to the direction of movement of the platform 20.

Through the design, the two driving assemblies 30 are respectively arranged on the side walls of the main body 11, and the whole driving assembly 30 is transversely arranged, so that the thickness of the side part of the platform lifting mechanism is low, and the whole size is small; on the premise of keeping high moving precision, the device has small size, simple structure and low cost.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, all according to the equivalent modifications and evolutions of the present invention, which are made to the above embodiments by the essential technology, and all belong to the protection scope of the present invention.
